Y surname MACHINE.

Application filed October 6,l 1923. Serial No. 666,930.

T0 all whom it may concern Be it known that I, VILLrAM E. `BAnLow, a citizen Vof the United States, residing` at Trevose, county of Bucks, and State of Penn- Sylvania, have invented certain new and useful Improvements in Swaging Machines, of which the following is a specilication, reference being `had to the accompanying dra-wings. Y

My invention rela-tes to machines useful for swaging articles of annular formation, and more particularly to altype adapted to swaging bands formed of sheet material such for example as paper, card board or 'metal The primary object of my invention isV to provide a machine capable of swaging articles of the character described in a continuous and rapid manner with assurance of l perfect uniformity in the results attained.

The detailed description which follows of a typical embodiment-of my invention will serveto make obvious other objects and attendant advantages, while the claims deline the scope of my inventioninso far as it is at present known to me.

In the drawings,-Fig. I is a perspective view of the swaging machine of my invention.

Fig. II is a plan view of the same with certain parts removed to avoid concealment of important details.

Fig. III is a detail sectional view taken as indicated by the arrows III- III in Fig. II. v

Fig. IV is a similar View but on a slightly larger scale taken. as indicated by the arrows IV-IV in Fig. II.v

Fig. V is a plan view of the assemblage of Fig. IV with some of the parts in sectional elevation; and

Figure VI is an illustration showing a container havingas one of'its constituent elements an encircling band capable of being swaged by the machine of` my invention.

As herein shown, the movable parts of my improved swaging machine are supported by a horizontal frame 1, preferably of structural steel sustained at a convenient height from the floor by a group of standards 2 suitably tied and bracedto lend the requisite rigidity to the structure., Journalled in ap.-

propriate bearings 3 adjacent one end of the frame 1 is a'tra'nsvers'c shaft 4 whereto is secu-red, at one extremity, a support for the articles being Vswaged in the form of a head 5 of annular configuration With a polygonal periphery affording a multiplicity of faces 6, which are centrally apertured and screwthreaded to receive -replaceable bushing cups 7 for accommodating and guiding radially slidable plunger holders 8. Normally these lecting receptacle 10, appropriately supported by the substructure of the frame l. Retraction of the plunger holders S is automat-ically effected throughv aid of compression springs 11, which individually encircle the ends of reduced axial prolongationsor stems 12 of said plunger holders that protrude inwardly through the bases of the cup guides 7. The springs 11 exert their inlluence against collars 13 adjustable along Y.

the threaded portions of the stems 12 and capable of being fixed in adjusted positions by nuts 15-16 of` which` the latter are rounded so as to ride easily about the periphery of a cam 17 disposed within the hollow of theY head 5. This cam 17 is supported by studs 18 projecting inwardly from longitudinal bar 19 of the frame 1, as best shown in Fig. V, and thereby held against rotation though traversed by the end of shaft 4. The cam 17, it willp'be noted, is substantially of spiral configuration with a decided notch at 20, permitting recession of thev plungers 8 under the Vaction ofthe springs 11.

Any suitable means maybe employed for imparting stepwise rotation to the head 5, one such means being herein exemplified as a pawling mechanism which includes a ratchet wheel 21, that is xed to the shaft 4 and arranged to be picked by a pawl 22 on the outer end of an arm Q3 free to oscillate on said shaft. Rocking movement is im parted to the arm 23 through a link connection 24 with ay crank 25 on the inner end of a shaft 2G which is joui-nailed in 'bearings 27 near the 'extremity of the frame l remote from that occupied by the shaft 4. Intermediate the bearings the shaft 26 carries tight and loose pulleys 28, 29 between which a driving belt may be shifted as required by a. shifter 30 capable of Vbeing 'actuated through the medium of I a hand lever `3l terni'inating in a handle '32 at the opposite end of the machine. n

Referring again to 'the swaging die 9, it will be noted that the same has its face recessed as at so as to telescopically engage over the end 'of the plunger holders 8 in the head 5 as s hown to best advantage in Figs. IV vand V, thereby to swage the interposed lband 13, the overlapping portions of the die 'and the plunger yholders 8 being appropriately rounded or otherwise configured to produce the desired s'wa-ginlg effect. This swag'in'g'die I9 is secured to one end of 'a longitudinally 'reciprocato'ry rod 3G vmounted in slide V'bearings `37 -3'8, and held 'against 'rotation through provision of a spline or feather 39. The rod 36 derives reciprocatory motion, in timed relationl to :the progressive shifting's of the head l5, from a rotary 'cano 40, fixed' to the outer end 'of the pulley shaft 26, which is effective upon an anti-friction roller 4l on a c'ollar 42fwhich -isse'curet'l tothe proximate end of 'said rod. rIhe roller 4l 'is at all times maintained in operative -contact with 'the cam 40 by 'a number of springs interposed between lthe collar 42 already referred to and another collar 44, free on the rod 35 and abutting against th'e `s"""l'e bearing 3S. l

As a 'means for ensuring maintenance of acci'irate alignmentand registry of the V"plunger holders 8 relative to the swag'in'g 'die 9 during the successive sw'aging 'operations, I employ a locking Vpin 45 (see Fig. V) which :successively enters apertures 46 in the 'side fa'ceoff a lateral annular flange 47 on the head 5, said apertures being uniformly =spaced circiimferent'ially, and, corresponding 'in number tothe plungerfholders '8. rIhe locking pin 45 is longitudinally slidable in a direction toward and 'away from the head '5, and guided in 'theboss 48 of bracket 49 bolted or otherwise ,secured to the frame l. @ne end of 'the locking pin 45 has an laxial cavity so 'as to be capable of rtelescopicrlly engaging a fixed 'horizontal stud 50 which assists guidance of said pin, the Ecavity also accoinniddates a compression sp1 ing 5I that is effective to yieldingly urge t'he 'pin`o'u`twar`dl Preparatory to each 'shifting of the head 5 the locking pin 45 is re- Itract'ec'l by 'means of a fsl'i'de 'bar whereof lone-extremity 'is beveled, as'at 53 in Fig. Il,

to afford a wedge cam designed to engage a roller 53 carried by saidlocking pin. The slide bar 52 is supported for longitudinal shifting jointly by the bracket 49 and 'a companion bracket 55, the former of these allor-ding anchorage for a headed stud 56 `which projects through a slot 57 in said slide bar, see Fig. V. The function of actuating "the slide bar 52 is vested in a rotary cam 58 which is mounted on the pulley shaft 26 immediately adjacent the cam 40 afore described and which is influential upon an anti-friction roller 59 on the contiguo-us end of said slide bar. l

In operation the vrings or bands "v B to tid be swaged are successively mounted onY the plunger holders S yof the head 5,4 and, through motion of the latter, successively presented to Ithe die 9 and swaging in a manner already explained. Charging' of the head 5 may be greatly facilitated by instal Alation of a hopper or receptacle such as shown at 60 in F ig. I wherein a quantity of the bands BA ca'n be stored. This hopper '60 has two of its adjacent side walls '6l-G2 'cut 'away at one cornerv and its bottom 63 slightly downwardly inclined to'wa'rv the head 5 at a convenient height so that the rings or bands B vmay be slid Volf at ya level even with the 'plunger holders 8 and thus readily impaled upon the latter.

An instance suggestive of practical application of my invention is in connection 'with the manufacture of paper containers S 'su'ch as represented, in F V I wherein Ithe swaged band B serves as a. strengthen 4ing member as well as an ornamentation, 'about the container mouth, the inwardly turned or swaged edge c 'preventing "displacement of ','said 'bandthro'i'igh forced engagement with the conical surface of the container shell. Y A
